Wrecks discovered on our previous technical diving trips, and new marks which we plan to investigate, are spread over an enormous area in the Gulf of Thailand. For this reason we run three main wreck diving trips - specifically to the North, East of Koh Tao. The northern route is shalower for less experinced tech divers whilst the eastern route is great for tri-mix divers, we try to always travel between marks overnight so we can spend a whole day diving and exploring each wreck .Each route is planned so that we can make at least two big technical dives each day.

The Naga is a beautiful wooden european sailboat with 8 double ensuite mahogany rooms. The boat has a fully equipped kitchen, lounge and dining area. The top deck has a spacious area to sunbathe. The boat is equipped with two brand new Bauer compressors, continous flow membrane nitrox system, tri-mix and partial pressure blending system. It has been recently refitted to accomodate 10 technical divers. All standard gasses, 50%, 100%, 18/45, 15/55 tri-mix available or other mixes available on request.

We run these trips over three days. Visiting some known wrecks such as teh HTMS Phangan and some large passenger cargo ships further north. This trip is great for Technical divers who have completed there DSAT Tec Deep, Tec 50 or TDI Extended Range courses or for divers wishing to complete there Tri-Mix course.
We can normally make at least two dives a day on each wreck, so 6 big tech dives over 3 days
Known wreck dives on our northern route include the H.T.M.S. Pha-Ngan, large Tanker, 2 huge cargo/passender ships, Unicorn and Torpedo wrecks.

This northern wreck diving trip is also perfect for trimix training, with the passenger/cargo ships possibly the "Pornsri" wreck at 77 metres.

Our eastern route is further out and the wrecks deeper so ideal for tri-mix divers, visiting wrecks such as the Big Boy wreck, Seacreast and some WWII to go check out
these wrecks are between 55 - 75 metres, so wreck dives on this eastern route are great for trimix divers or trimix diving courses. 
The eastern wrecks include our known wrecks such as big boy and the seacrest drill ship and some WWII wrecks we haven't yet reached including Tottori Maru, Araosan Maru, Akela Maru, Nanmei No.5 Maru and Sakura Maru.
